I looked in my 49th and found data for 7 different jacketed bullets and 5 different cast bullets, each with at least 5 different powders. Cast lead data is more dependent on bullet weight not shape. It is OK to use "linotype" data for 10 BHN and higher bullets. PCed/Hi-Tek bullets use cast lead data and I have always used cast bullet starting data for any plated bullets I reloaded. The jacketed bullet data in my 49th is for 110. gr HP to 180 gr. JHP. Again weight is the main consideration for load data and FMJ, JHP, and JSN bullets can use the same starting load data. But the main key is to start every new to you load (bullet, powder, primer) with the book starting loads. Work up if necessary. I could reload for 12 different bullets and about 9 different powders with just the data in my 49th, including my bullets cast from my "Mystery Metal" bullet alloy...I just need a bit of advice. My Lyman handbook 49th edition has very little data on the different projectiles available. Mostly plated HP and a few Linotype bullets but not the shape I’m interested in.
